28th November 2019 Reviewed by Angela Cheetham Wilkinson Love the colours, the flexibility, the fluidity, such lively work has been achieved by novices I’ve been working with - but - some of the tops on the previous purchase of this product are truly stuck!

11th July 2019 Reviewed by Shauna Cox I think it's best used to create washes rather than precise painting. I'm still learning how to use the product so that trouble could just be with my ability to use it. The paint is very vibrant however and I do like it. Reactivation can be difficult though.
